  • Publication number: 20160186545
    Abstract: A method for recovering oil from an earth reservoir includes injecting low salinity water into the reservoir using a low salinity water injection system, the low salinity water having a salinity that is less than connate water of the reservoir or normal water that was injected in a previous water-flooding process, the normal water having a salinity that is within plus or minus ten percent of the reservoir connate water. The method further includes injecting an immiscible gas into the reservoir using an immiscible gas injection system following the injection of the low salinity water, the immiscible gas being immiscible to the low salinity water and the oil in order to recover the oil.
